摘要
当深大基坑距离地铁隧道较近时,对地铁隧道的影响要加以控制,并采取有效措施使基坑开挖对地铁隧道的影响减小。论文针对广州某邻近地铁六号线的基坑设计、施工和监测资料,应用有限元方法,研究了深大基坑分区开挖对既有地铁隧道的影响,其分析结果可为优化设计和施工提供有益参考,为类似工程提供借鉴。
It is necessary to take effective measures to reduce the influence of excavation on metro tunnel when the deep and large foundation pit is relatively close to metro tunnel. The impact of blocked excavation unloading in deep and large foundation pit upon metro tunnel was analyzed by using finite element method combined with design, construction and monitoring data of a foundation pit construction near Guangzhou Metro Line 6. The analysis results can provide beneficial reference for optimization design and construction, also to provide reference for similar projects.
